Abstract (en)
[origin: EP3425753A1] To increase the reliability of an LD module without decreasing the efficiency of coupling between the laser diode and the optical fiber, an LD module (1) includes a light-guiding device mounted therein that includes (i) a dividing optical system (DM) configured to divide a laser beam so as to generate a partial beam group and (ii) a compositing optical system (RM1, RM2, PRE, PBC) configured to composite the partial beam group so as to generate a partial beam bundle including a plurality of partial beams each having an S axis parallel to a particular spatial axis.
